Scythe Big Shuriken 3 Rev.B CPU Air Cooler, 120mm Low Profile (67mm Tall), Intel LGA1700, LGA1151, AMD AM5/AM4/Ryzen

Product Information

The sound level in dBA was measured 10 cm from the intake fan with the fan speed set to 100%. Then, the sound level was estimated for other distances using the following formula:

The build quality of the Big Shuriken 3 is quite good, everything works as intended, and even with the minor issues we ran into with a specific set of components, it is unlikely that many will run into what we did in the first place. However, it did have us feeling the pain of any LGA2011.2066 users, where quad-channel memory will need to be standard height. Warranty information is printed on the left side and on the right, we see a few words about both the heatsink and the Kaze Flex Slim 120 PWM fan used. Would I reduce the PPT, TDC, and EDC in BIOs? I've never done this before. Could you link me a guide that you find helpful? Thermalright can easily improve this cooler compatibility if they provide a way for users to install the cooler in Up/Down orientation, which you can't on AM4.

The noise of the Big Shuriken 3 paired with the slim Kaze Flex fan wasn’t the best and was basically identical to the Fuma with a standard Kaze Flex fan. The Big Shuriken 3 is a relatively dense heatsink and it’s paired with a higher RPM fan, so more noise is expected. However, these readings were done on an open test bench with the fans at max speed, so this is the worst-case scenario. So, having a typical enclosed PC at an average distance away would result in almost all the heatsinks in the chart below being reasonable, even at max fan speed. Nothing out of the ordinary to cause alarm about the noise levels here. The cooler has pretty good noise levels, even under high load. Max noise is about 41 decibels, which is quite low and shouldn’t bother anyone sans those users who can’t bear any sound coming from their PC. The cooler comes with a low noise adapter that decreases noise even further but lowers performance a bit. Building a SFF (small form factor) PC based on an Mini-ITX board carries certain limitations with it. One of the biggest limitations is the CPU cooler height, which has to be shorter than what you have on regular air CPU coolers since most Mini-ITX PC cases are much smaller than regular cases. And finding the best low-profile CPU cooler can be a bit complicated since not all are made for every CPU. Why estimate sound level instead of measuring at further distances? It’s because the meter I’m using is most accurate between 40-130 dBA, so I needed to measure really close to the source to make sure my readings were within that range to get the most accurate measurements. Results Cooling Performance

Long story short, if you use a left handed A4 sandwich style case with Gigabyte board on AM4 platform, this cooler will be a headache to install.

Also in confined spaces, airflow is a premium, and not just in how the chassis provides the influx of ambient airflow, but what in the system can be actively cooled. With the C-Style design, you almost get three coolers in one. Many cover some if not all of the memory, of course, they cool the CPU, but they also add direct airflow to the PWM of the motherboard. How many towers or AIOs can say that? Even more importantly, can they fit in an SFF chassis or Mini-ITX system? Also, if it doesn't work well, there are things you could do, like reducing the PPT, TDC, EDC settings, to make the 5800X consume less power without losing much performance, and in typical gaming workloads, it's not going to consume much more power than your current CPU anyway. I've tried daily driving my 5900X at "65W TDP" values (88 PPT, 60 TDC, 90 EDC) just to see how it does and I get about 85% of the multicore performance with no loss in single core performance. I don't even notice a difference in games. One downside of the Big Shuriken 3 is that it’s marketed as a great cooler for HTPC and SFF builds, but its height renders it incompatible with some popular SFF cases. So, make sure you aren’t planning to use one of the following cases for your SFF build: Scythe remains a household name in the air cooling segment of PC hardware due to its well-received heatsinks and fans over the years. Today, we have Scythe’s Big Shuriken 3 which is a low profile cooler aimed at small form factor (SFF) builds and touts a “zero interference” claim for motherboard and RAM. Let’s see how well it holds up against a testbed full of tower heatsinks and all-in-one liquid coolers.
